Festo
3478
Quick coupling plug KS3-CK-6
The Festo industrial component, part number 3478, features a 4.9 mm nominal width and an operating pressure range of -0.095 MPa to 1.2 MPa (-0.95 bar to 12 bar / -13.775 psi to 174 psi) across its entire temperature span. Weighing 21 g with a RoHS-compliant build comprising nickel-plated brass and an anodized wrought aluminum alloy union nut, it delivers a normal nominal flow rate of 216 l/min to 464 l/min (standardized to ISO 8778 at 234.1 l/min to 503 l/min) utilizing compressed air according to ISO 8573-1:2010 [7:-:-]. This unit accommodates pneumatic tubing with an 8 mm outside diameter or a barbed fitting with a 6 mm inside diameter using a union nut, operates in ambient temperatures from -10 °C to 60 °C, and allows lubricated operation while meeting CRC 1 low corrosion stress and VDMA24364-B1/B2-L LABS conformity.

Request a QuoteWhy no listed price?
Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.
